Secondary  cities  in  developing countries  are  becoming  the  hub of  livelihood  opportunities  which
attracts  rapid  economic  growth, high population density and thereby high  disaster  risks.  Urban  centers, industries,  informal  small  scale businesses  and  urban  population settlements are blooming in ad hoc manner  without  following  proper land-use planning. Due to economic,
social  and  political  pressures  the urban  poor  are  forced  to  live  in hazard prone areas rendering hem more  vulnerable  to  disasters.  The analysis of natural hazards in South and  Southeast  Asia  indicates  that geologically triggered hazard events such as earthquakes and tsunami are
responsible for higher consequences in terms of damages losses, but are comparatively low frequency. Hydro-meteorological  events  are  more frequent and more widespread within South and South East Asia.
